Most reported works on generating d-MPs are based on minimal paths (MPs for short). Currently, all reported MP-based algorithms generate duplicated d-MPs during the search process and additional recursive comparison is required to remove those duplications. However, the number of duplications increases substantially with the size of network. Thus, a more efficient algorithm is needed to search for all d-MPs without duplications. In this study, we proposed an improved algorithm based on the breadth-first search to search for d-MPs without duplications. The mechanism on generating duplicated d-MPs is investigated. A novel approach is incorporated into the existing algorithm to generate the d-MPs without duplications. Through computational experiments, it is found that the proposed algorithm is more efficient than existing algorithms for finding all d-MPs.","PeriodicalId":317626,"journal":{"name":"2017 Second International Conference on Reliability Systems Engineering (ICRSE)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126519976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been reported that the evaluation of multistate system reliability is an NP-hard problem. Thus, it is important to find an efficient method to analyze the reliability of such systems. In this paper, the multistate multivalued decision diagram (MMDD) method is used to evaluate the system reliability given all minimal path vectors (d-MPs for short). Because the size of the MMDD is highly affected by the order of the components, which ultimately affect the efficiency of the method. Two ordering heuristics are proposed for ordering components in d-MPs before they are used to develope the corresponding MMDD. Illustrative examples are provided, which validate the correctness and advantages of the proposed heuristics.","PeriodicalId":317626,"journal":{"name":"2017 Second International Conference on Reliability Systems Engineering (ICRSE)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125021971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the running states of evaluation object are considered, including normal state and fault state. Markov model is established to describe the system's state based on the states of transmission lines and distribution system, and transition probability between states can be obtained through the historical running data. Then, the hierarchical analysis method can be applied to analyze the influence on the load point made by the status of each element. The fault set of the load point to be evaluated is represented by the status of each element. In addition, the Markov chain to be established is expressed by probabilistic model checking tool and the reliability indexes are expressed by property specification. The reliability indexes can be obtained through verifying the property specification. Finally, a typical radiant power distribution system is proposed as an instance to verify the effectiveness of the method.","PeriodicalId":317626,"journal":{"name":"2017 Second International Conference on Reliability Systems Engineering (ICRSE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129494004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, some researches on the relationship among EOS (Electrical Over Stress), EM(Electro-migration) and ESD(Electrostatic discharge) have been completed. By study about the methods of failure analysis of plastic encapsulated MOS component, SAM (Scanning Acoustic Microscope) and SEM(Scanning Electron Microscope) are identified as the most important methods in failure analysis. According to the achievement of these researches, the procedure of failure analysis has been optimized by adding microscopy sample preparation. This improvement makes the analysis in chip surface extend to chip-section. In the case study, with this new procedure, a plastic encapsulated MOSFET has been analyzed. As a result, this failure is caused by the source-drain breakdown.

The remaining parameters were used to construct the life cycle cost estimation model of support device. In terms of efficiency, the calculation methods of the utilization rate and the satisfaction rate were given, and allocative efficiency is taken as the evaluation index. The cost-efficiency model is established to determine whether the intensification is feasible.

Besides, response surface model (RSM) is constructed to reduce the computational cost of RBDO. Results show that in deterministic optimization (DO), the reliability of mass flow rate is only 0.7843 while in RBDO the reliability of mass flow rate reaches 0.9976.
